Abstract: One of the key challenges in internal combustion engine is how to simultaneously improve combustion behaviour and performance characteristics. In this light, research has evolved on the modification of design parameters and development of new fuels. To this end, blends of biodiesel from orange peel oil-base biodiesel and neat diesel (B10, B20, B30, B40, B50, B60, B70, B80, B90 and B100) were used to study the combustion and performance characteristics of diesel engines. Diesel-RK software was used to model a four stroke, single cylinder, water cooled, direct injection, diesel engine of Kirloskar make - the combustion and performance parameters were studied for an engine speed of 1,500 to 3,500 rpm, at full load condition. The result showed similarities in behaviour of pure diesel, biodiesel and its blends. In comparison with diesel, the cylinder pressure, heat release rate, ignition delay and brake power were lower, for orange peel oil-base biodiesel and it blends while brake specific fuel consumption, and volumetric efficiency were higher. The study concludes that orange peel oil-base biodiesel has the potential of replacing pure diesel; and that optimal performance and combustion is possible when the biodiesel is 10% in the biodiesel/diesel volume blend (B10).
